1) first, we have to convert the grams to moles of AuCl3 using the molar mass of the molecule.
molar mass of AuCl3= 197 + (35.5 x 3)= 303.5 g/mol
73.4 g (1 mol AuCl3/ 303.5 g)= 0.242 moles
2) now. let's convert moles of AuCl3 to moles of chlorine gas (Cl2) using the mole-mole ratio
0.242 mol AuCl3 (3 mol Cl2/ 2 mol AuCl3)= 0.363 mol Cl2
3) finally, we convert moles to grams using the molar mass of Cl2.
molar mass of Cl2 = 35.5 x 2= 71.0 g/mol
0.363 mol Cl2 ( 71.0 g/ 1 mol)= 25.8 grams
Answer: Electrolyte Solutions
At STP, a powered 4.0-gram zinc sample would react fastest dilute hydrochloric acid.
The net ionic equations in
the creation of solid Hg2Cl2 and aqueous Sodium Nitrate (NaNO3) would be:
Hg2(NO3)2 + 2 NaCl
--------> Hg2Cl2 + 2 NaNO3 <span>
Hg2+2 + 2NO3-1 + 2Na+ Cl- ----> Hg2Cl2 + 2Na+ + 2NO3-1
<span>Hg2+2 + 2Cl-1 ------------> Hg2Cl2</span></span>
